The Recovery Factors Analysis of the Human Errors for Research Reactors

Abstract

The results of many Probabilistic Safety Assessment (PSA) studies show a very significant contribution of human errors to systems unavailability of the nuclear installations. The treatment of human interactions is considered one of the major limitations in the context of PSA. To identify those human actions that can have an effect on system reliability or availability is necessary Human Reliability Analysis (HRA). The recovery factors analysis of the human action is an important step in HRA.

This paper presents how can be reduced the human errors probabilities (HEP) using those elements that have the capacity to recovery human error.  The recovery factors modeling is marked to identify error likelihood situations or situations that conduct at development of the accident.

This analysis is realized by THERP method [1]. The necessary information was obtained from operating experience of research reactor TRIGA from Institute for Nuclear Research, Pitesti. The required data were obtained from generic databases.
